(UNDATED) - Indiana is among states with the highest percentages of uninsured drivers across the United States.

That's according to a new report by the Insurance Research Council.

The report says the number of uninsured drivers across the U.S. has risen along with the recession.

The report says 16% of Hoosier drivers don't have insurance.

Research Director Patrick G. Schmid says insurance enforcement varies from state to state.

Schmid says during the recession, many who've lost their jobs simply cannot afford insurance or choose not to pay for it.

Schmid says uninsured motorists end up costing insured motorists more in premiums.

The report shows the states with the highest number of uninsured drivers are Mississippi -28%, New Mexico-26%, Tennessee-24%, Oklahoma-24%, and Florida-24%. States with the lowest percentages include Massachusetts, Maine and New York which hover between 4 and 5%, according to the report.
